FLESHING MACHINE.

Applicationflled April 14., 1923. SeriaLNo. 632,071.

To all whom it may concern:

Be it known that I, ALBERTUs TRAvIs, a

citizen of the United States, residing at provide corrugated and rubberrolls mounted in a new and novel manner for directing the hides to theknife cylinder.

A further object is to mount the knife cylinder adjustably so that itcan be minutely shifted toward or from the hide being treated.

A still further object is to provide yielding means for actuating thesaid rolls relative to the knife cylinder so as to adapt them to hidesof different thicknesses.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combination of parts whichwill be hereinafter morefully described and pointed out in the claim, it being understood thatvarious changes may be made in the construction and arrangement of theparts without departing from the spirit of the invention as claimed. Inthe accompanying drawings the preferred form of the invention has beenshown- In said drawings:

' Figure 1 is a plan view.

Figure 2 is a front elevation.

Figure 3 is a side elevation.

.Figure 4: is an elevation with the drive mechanism removed, the feedroll being shown in active position relative to the fleshing or knifecylinder, the parts of the machine being removed on the lines-4: Figure1.

Figure 5 is a section on line 55 Figure 1.

Figure 6 is a section on line ure 4:.

Figure 7 is a section on line 77 Figure 6.

Figure 8 is a section on line 8-8 Figure 1.

Figure 9"is a section on line 9-9 Figure 8. I

Referring to the figures by characters of reference 1 designates theside frames or standards of the supporting structure, these beingpivotally connected as by means of a rod 2 and a rear beam 3. Each framehas an upwardly extending portion 4 near the front thereof formed with aslot 5 and in the top of this portion 1 is provided a bearing 6 in whichis journaled the shaft 7 of a corrugated main feed roll 8.

Studs 9. are extended laterally from the standards 1 and mounted toswing'thereon are arms 10 each of which has a pair of bearings 11 and 12at its upper end. Journaled in the bearing 11 is the shaft 13 of arubber pressure roll 14; while the shaft 15 of a supplemental corrugatedfeed roll 16 is journaled in the bearings 12. See Fig ure 1. The shafts13 and 15 extend through and are adapted to swing within the slots 5,the rolls. 14 and 16 being interposed between the extensions 4.

Shaft 7 is provided near one end with a gear 17 and a gear 18 is alsoprovided on one end portion of shaft 13. This gear is designed to swinginto and out of mesh with 7 gear 17 when the arms 10 are swung back andforth respectively.

Another gear 19 is secured to shaft 7 near its other end and is adaptedto be engaged by a gear 20 secured to one end of shaft 15. Thus when therolls 14 and '16 are swung toward the roll 8 gear 20 will be.

brought into mesh with gear 19 While gear 1 18 will be brought into meshwith gear 17.

The shaft 21 is journaled in the rearportion of the standards 1 andsecured to this shaft close to the outer side of each standard is aneccentric 22 engaged by a split strap 23 from which extends an arm 24.

A longitudinal slot 25 is formed in the arm and slidably mounted in thearm is a rod 26 pivotally connected at 27 to the adj acent swing arm 10.A coiled spring 28 is mounted on each rod 26 within slot 25 and bears atone end against one wall of the slot and at its other end against a nut29 adjustably mounted on the rod. Thus the springs on the two rods serveto hold the arms 10 normally swung toward arms 24. This swingingmovement can be limited by stop nuts 30 adjustably mounted on the rods26. andadapted to bear against arms as. I

- 9. Arm 38 is connected to a rock shaft 39 extending from the rear tothe front of one of the standards l and provided at its front end with afoot pedal yieldingly supported by a spring 41 suspended from a bracket42. "A disk43 is carriedby and rotates on the sha'ft21 and has a recess44 in one facethe "peripheral wall of which is formed with anannular-series of teeth'45. A collar46 rotates with'shaft 21 and isseated in recess 44, this collar being provided with adog 47 pivotallyconnected thereto as at 48 and normally pressed outwardly by a spring 49carried by the collar. Tripping studs50 are extended from the respectiveend portions of the cross head 33and are adapted to project into recess44 so as to be engaged successively by the dog during the rotation ofthe collar 46and shaft 21. A large pulley 51 and a small pulley 52 areconnected to and ro-' tate with disk 43, the disk and pulleys beingnormally mounted for'free rotation on shaft 21.1 [Under normalconditions the dog 47 is pressed against one'of the studs 50 so thatdisk 43 can rotate freely on theshaft 21.

;By.,depressing foot pedal 40' arm 38' will swing and cause thecrosshead 33 to slide on shaft 21,. thereby withdrawing studs 50 from thepath of dog 47 Consequently spring 49 will throw the dog into engagementwith one :50 will be stopped. This rotation of the shaft willbesufiicient to cause the eccentrics 22 to pull rods 26 longitudinally,thereby to swing arms 10 toward shaft7 and roll 8. The skin "ithisgripping operation.

pedal 1s next depressed so as to again re or hide to be fleshed is firstplaced over the rolls 14 and 16 and obviously this movement of the arms10 will cause the hide to'be gripped between the rolls 8 and 16while, atthe same time, gear 20 will be brought into mesh with gear 19 andbrought into mesh will gear17; Should the hide'be of uneventhickness oneor the other of the springs 28 will be free to yield during lease dog 47the shaft 21 will make another one-half revolution which will'besufiioient in Figure 1. we rdly from'the'standards 1 and journaled gear18 willrbe When the foot to swing the arms 10 back to the position shownin Figure 3. a

Each of the standards 1 has a bearing 53 slidably mounted thereon andjournaled in these bear-ingsis the shaft 54 of a fieshing cylinder '55on which are provided knives 56 preferably curved as illustrated forexample Arms 57 are extended uptherein is an. adjusting screw 58parallel with shaft 54 and having oppositely threaded portions 59 and 60engaging oppositely pitched wedging blocks 61. These blocks are slidabletransversely of the standards ;1 infront of the respective bearings 53.It

will be obvious, therefore, that by rotating screw 58 in one directionthe-wedges 61.,will be drawn toward each other, thus "to force thebearings 53 toward slots 5. By rotating the/screw in the oppositedirection. the

wedges will be moved apart andfthe shaft 5 4 is thus free to slide orshift backwardly away from the slots 5. Each of the standards ispreferably formed with'anupstanding abutment 62 for one of the wedgeblocks 61. A hand wheel 63 or the like can be secured toone end of thescrewto facilitate the rotation thereof.

Shaft 54 constitutes the drive shaft of the machine and has a pulley 64at oneend'for engagement by a drive pulley. A pulley 65 is carried bythe other end of the shaft and is adapted to transmit motion throughabelt 66 to a pulley 67 mounted for rotation on a stud 68projectinglaterally from one of the standards 1. A gear 69 rotates withpulley 67 andmeshes with a gear 70 carried by a stud 71 projecting fromsaid standard 1. .A

pulley 72 rotates with gear 7 O and is adapted to transmit motionthrough a belt'73 to the pulley 51. Another belt 74 is used for.transmitting motionfrom the icy 75 secured to the shaft 7. i

In using the machine shaft 54 is rotating constantly and, consequently,"motion is being transmitted constantly through the belts and pulleys andthrough the gears69 and7O to the shaft 7 and pulley 51" as well as disk43.

The operator places the hide "or skin'on the rolls 14. and 16. Footpedal 40 is depressed momentarily so as to cause the arms 10 to swingrearwardly and grip the hide between the rolls 16 and 8. At the sametime the gears 20 and 18 will be brought into mesh with the gears 19 andl7 respectively so that while roll 8 is rotating in a elookwisedirectionwhen viewed as'in Figure 3, the other rolls 14 and 16 will be rotated ina counterclockwise direction. The two rolls 8 and 16 pulley 52 to a pul-1.100 upward direction and when the entire surface has been treated thefoot pedal 40 can be depressed momentarily as heretofore explained so asto cause the arms 10 and the rolls carried thereby to swing forwardly totheir initial positions. By means of the adjustment provided for thebearings 53 and illustrated in Figures 6 and 7 the fleshing cylinder canbe shifted minutely toward the hide so as properly to engage the same.

What is claimed is:

In a fleshing machine the combination With a supporting structure, afeed roll, a

fleshing cylinder, and means cooperating with the feed roll fordirecting a hide to the fieshing cylinder, of slidable bearingssupporting the flashing cylinder, and means for simultaneously shiftingthe hearings to adjust the fieshing cylinder relative to the feed roll,said means including opposed Wedge blocks engaging the respectivebearings and an adjusting screw having oppositely fixed threads engagingthe respective blocks.

In testimony that I claim the foregoingas my own, I have hereto aflixedmy signature in the presence of two witnesses.
